Rather than wait for nations to increase their infrastructure or for land-based technology to progress, Musk proposes going from 51% to 100% using a single system.

How does it work? Quite simply by blanketing the globe in a vast network of over 10,000 satellites.

SpaceX has already launched two test satellites affectionately named Tintin A and Tintin B.
